Alexey went above and beyond! We called him for a mold issue in our home and he was intentional about assessing addressing the issue accordingly. He is knowledgeable and super friendly. Will definitely call for our next home project! 10/10 recommendation.

We contacted this company to inspect our house for molds. After the inspection he explained the actual problem. No mold was detected; simply cleaning the walls and the rest of the area will resolve the issue. The owner/gentleman was so honest and very truthful & dependable . I highly recommend him. Thank you.

Thank you so much for your thoughtful review and for trusting us with your inspection! We truly appreciate your kind words.
Honesty and transparency are core values of our company. If a home doesn't need mold remediation, we'll always say so rather than recommend unnecessary work. We're glad we could help identify the actual issue and point you toward the right solution.
Thank you again for your trust and recommendation. If you ever need help with water damage, mold remediation, reconstruction, or any future home projects, we'll be happy to help. Wishing you all the best! 🙏

Alexey is very nice and professional. He did a through job of inspecting and spraying areas exposed by my other contractors who do not spray to prevent mold regrowth. Since my house is being repaired and remodeled in stages, I will have him come back and spray the other rooms when we get to those.

Thank you so much, Robyn! 🙏 It was truly a pleasure meeting you and helping with your home. I really appreciate your trust and the kind words. I’m glad we could take care of the exposed areas properly, and I’ll be happy to come back as the remodel progresses and help with the next rooms as well. Wishing you the best with the rest of the project, and I look forward to seeing you again! 😊🏠

Owner of this company is professional, courteous, honest and does a great job. We hired to patch some drywall in our garage.
The patch looks great and we will hire California Construction again for any work we may need.

Alexey did a great job on a large backyard concrete area with mold in areas. The job was bigger and more difficult than it appeared on video and in pictures. We renegotiated a fair price and he spent hours cleaning the dirt and mold off the concrete. It looks so much nicer and I’m very happy with the result. I appreciated his quick response, quick scheduling, transparency, hard work on the job and great result.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
Pricing depends on the scope of work, project size, site conditions, and materials required. We provide clear, upfront estimates with no hidden fees.
Many smaller projects can be quoted from photos or videos. Larger, more complex, or insurance-related projects may require an on-site inspection to ensure accurate pricing.
Our goal is to provide fair, transparent pricing while delivering high-quality workmanship and long-lasting results.
What is your typical process for working with a new customer?
The process usually begins with reviewing photos or videos to understand the project and provide an initial assessment.
If needed, we schedule an on-site inspection to evaluate the conditions, take measurements, discuss the scope of work, and answer any questions. A detailed estimate is then provided before any work begins.
Once approved, we schedule the project, complete the work efficiently, keep the job site clean throughout the process, and perform a final walkthrough to ensure everything meets expectations.
What education and/or training do you have that relates to your work?
California Construction Pro Service is led by Alexey Voronov, who has an engineering background and nearly 20 years of construction experience. Before operating in the United States, he spent more than 15 years managing a construction company and leading residential and commercial renovation projects.
Alexey is also an IICRC-certified Water Restoration Technician (WRT), Registrant #70267276, with professional training in water damage restoration, moisture inspection, structural drying, and proper restoration procedures.
Our team continues expanding its expertise through ongoing professional training in water damage restoration, mold remediation, reconstruction, and general construction.
